1. To request the Technology and Economic
Assessment Panel (TEAP), in its May 2010 Progress
Report and subsequently in its 2010 full assessment, to
provide the latest technical and economic assessment of
available and emerging alternatives and substitutes to
HCFCs; and the Scientific Assessment Panel (SAP) in its
2010 assessment to assess, using a comprehensive
methodology, the impact of alternatives to HCFCs on the
environment, including on the climate; and both the SAP
and the TEAP to integrate the findings in their
assessments into a synthesis report;

Domestic refrigerators and freezersDomestic refrigerators and freezers
About 63% of new refrigerators employ HFC-134a
About 36% employ hydrocarbons, mainly HC-600a
(isobutane)
It is predicted that, within 10 years, under business-as-
usual, at least 75% of all new production will apply
hydrocarbons; required changes in standards are
underway and regulations could ease transition
